چکیده انگلیسی
In-doped ZnO nanometer thick disks were successfully fabricated by thermal evaporation of a powder mixture of Zn, In2O3 and graphite without catalyst. SEM images show that some ZnO disks have perfect dodecagon shape. These disks are about 1∼3 μm in size and 40∼100 nm in thickness. XRD, TEM and EDS observations show that the disks are single-crystalline ZnO with wurtzite structure. The disks grow mainly along the twelve symmetric directions of <21¯1¯0> and <101¯0>, while the growth along [0001] is suppressed. The In content of the disks reaches 27.4 at.%. Room temperature photoluminescence spectra show that the UV emission peak blueshifts and become broader after doping.
